How to properly raise OpenCart on CentOS 7?

Question

CentOS

Raised on a CentOS 7 virtual machine with MySql+php7+apache. I uploaded OpenCart, and when I run ".../www/install/index.php" it gives errors from the file ".../www/system/library/session/file.php":

Mistake:

Warning: fopen(/web/***/www/system/storage/session//sess_3b7b8c69c3e79b35f77297c627): failed to open stream: Permission denied in /web/***/www/system/library/session/file.php on line 29
Warning: flock() expects parameter 1 to be resource, boolean given in /web/***/www/system/library/session/file.php on line 31
Warning: fwrite() expects parameter 1 to be resource, boolean given in /web/***/www/system/library/session/file.php on line 33
Warning: fflush() expects parameter 1 to be resource, boolean given in /web/***/www/system/library/session/file.php on line 35
Warning: flock() expects parameter 1 to be resource, boolean given in /web/***/www/system/library/session/file.php on line 37
Warning: fclose() expects parameter 1 to be resource, boolean given in /web/***/www/system/library/session/file.php on line 39

Answer 1

"Permission denied" - it says right there in black pixels on white - there are not enough permissions.
Check folder permissions. Most likely, the user under whom the web server is running does not have rights to this folder.
Correct this mistake, and others may follow.
